United States Patent 7 SMOKING PIPE wrrn IMPROVED FILTERING flM Arthur GQTayIor, Washington, Kans. Application November 1, 1954, Serial No. 465,911

1 Claim. or. 131-194 The present invention relates to a tobacco smoking pipe whichis novelly constructed in that it is provided with filtering means which is structurally and functionally unique.

In carrying out the principles of the instant concept, a readily accessible exteriorly arranged cartridge-like filter is provided. It is preferably an economical U-shaped plastic or equivalent tube charged with an appropriate filtering material. The end portions of the tube are readily attachable to and detachable from cooperating openings provided therefor in complemental portions of the stem adjacent the junctural union between the stem and bottom portion of the complemental bowl. With this arrangement, one may purchase one or more filters with the idea in mind that because they are individually inexpensive, he can aiford to throw away a filter whenever it appears to be unfit for continued use.

Another object of the invention has to do with a special block-like formation or reinforcing member which provides what is believed to be the extra mass between the bowl and stem and not only provides a satisfactory mount for one end of the tube, but provides the added or needed material through which a bore or passage may be formed in order to obviate the necessity of ruinously boring a hole through and weakening the wall of the bowl.

Another object of the invention has to do with an integrated bowl and stem wherein the only discharge for smoke from the bowl is by way of the restricted upwardly and rearwardly inclined passage leading to the by-pass and filtering tube, the discharge branch or end of the latter communicating with a chamber at one end of a socket formed axially in the stem, the immediate region between the bottom of the bowl and stem being solid and providing what has sometimes been treated in the art as a blind passageway between bowl and stem.

Then, too, novelty is predicated upon boring passages at right angles to each other in the stem with one providing a socket and the other a chamber at one end of the socket, there being an apertured partition between the chamber and socket.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of illustrative drawings.

In the drawings, wherein like numerals are employed to designate like partsthroughout the views:

Figure 1 is a view in section and elevation of a tobacco smoking pipe constructed in accordance with the principles of the present invention;

Figure 2 is a top plan view of the same; and

Figure 3 is a perspective view of the U-shaped filter or, as it is alternatively called, a smoke by-passing and filtering tube.

Referring now to the drawings with reference numerals and accompanying lead lines, the over-all pipe is characterized by three distinguishable components or units; namely, A, B and C.

Unit A is a wooden or equivalent bowl and stem. The

2,776,663 Patented Jan. 8, 1957 cc v bowl is denoted specifically at 4 and is of more or less conventional design in that it includes a cavity providing a tobacco receptacle 6. The lateral stem is denoted at 8. The stemis substantially solid at 10 where it has principal connection with the bottom of the bowl. The right hand end of the stem has an axial bore therein, which is here conveniently referred to as a socket 12, and the principal portion of this is intended to accommodate the insertable and removable or telescoping shank 14 on the customary bit 16. The socket is here shown as having a partition 18 between the ends with the partition centrally apertured at 20 to allow the smoke to pass into the shank 14. The portion of the socket to the'left of the partition is shown as a chamber 22, and this has a smoke intake opening 24 which opens laterally through the peripheral surface of the stem 8. This opening serves to accommodatethe branch or end portion 26 of the U-shaped filtering by-pass C. The filtering material therein is .at 28. The opposite branch or end portion which is shorter than the one denoted at 26 is here distinguished by the numeral 30, and it fits into an opening 32 provided therefor in a mound-like mount, or as it is better known, a reinforcing block which constitutes a juncture between the stem 8 and coacting end portion of the bowl 4. This is of step-like form and is denoted at 34. This added mass at this vulnerable point increases the thickness, as it were, of the bowl and makes it possible to provide the bore or passage 36. The latter is diagonal and has one end portion 38 in communication with the central bottom of the bowl or receptacle and the other end portion communicates with the branch opening 32. Thus, when the tube end 30 is fitted telescopically into this opening, communication is had between the upwardly and rearwardly inclined smoke passage 36, the filtering and by-passing U-tube C and the chamber 22.

it is to be again stated that this unit C is a readily attachable and detachable part. It is to be inexpensively made and preferably of an appropriate grade of commercial plastics. This means that it may be bought in lots of a half dozen or more in a carton or box for handy use. Just as soon as one by-passing and filtering tube becomes unfit for use, it can be removed and thrown away and replaced with a fresh one.

It is realized, of course, that by-pass tubes aflfording an indirect passage of smoke from a pipe bowl to a stem are not new. Previous patents have been granted on such devices. It is to be noted, however, that if it becomes necessary to bore an opening through a thin walled bowl, the bowl may crack or may be entirely too fragile for such work. It is important, therefore, to include sufi'icient mass in the over-all unit A that the junctional block or reinforcing member 34 provides not only a satisfactory foundation and mount for the adjacent end portion of the filtering tube, it provides the extra material needed to form the bores 32 and 36 in the manner illustrated in the drawings. Then, too, the design employed in achieving this end makes for a more rigid and stronger pipe construction. Not only this, since the tube has to be detached and replaced, the constant changing of tubes requires a sturdier construction which is exemplified in that herein provided.

Since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

A tobacco smoking pipe comprising a bowl having the usual receptacle portion for reception of the charge of smoking tobacco, a complemental lateral stern having one endtportion integral with thebottom of saidbowl, a steplike junctional portion joined integrally with an exterior of the well" portion of" the bowl and a limited top portion of the stem and providing a reinforcing member at the juncture of the-.bowl and stem, said stem and memberhavingan upwardly andrreanwardly inclined smoke egress passage communicatingat one end with the bottom of the bowl and having its other end. registering with a vertical branch which opens through thetop side of said step-like reinforcing member, said stem having an axial socket formed? therein one end of which opens through the corresponding end of the stem, said socket being provided intermediate its-ends with a ported partition and. said partitionrcooperatingtwith anadjacent. end of said socket and providinga smoke trapping chamber, the latter having a smoke inlet port opening through the cooperating peripherallsurface of the stem and being spaced from said steplike member as well as the vertical branch of the smoke egress passage, the, entire portion of the step between said chamber and smoke egress passage being solid, a U-shaped filtering tube of throw-away material, said tube having filtering material therein and being readily at- References Citedlin-thefile of this patent UNITED STATES PATENTS 1,468,124 Molloy Sept. 18, 1923 1,481,235 Smith- Jan. 15,1924 1,884,039 Marin Oct. 25, 1932 2,183,658 Schnaier Dec. 19, 1939 2,228,381 Aldeman Jan. 14, 1941 2,472,444 Smatt June 7, 1949 2,564,799 Anderson et al Aug. 21, 1951 2,585,390 Knight Feb. 12, 1952 2,607,354 Wilson Aug. 19, 1952
